· Three bulk properties (type of cargo, moisture content, and pre-consolidation) are responsible for the variations of the dependent bulk properties. Various dependent bulk properties, including bulk density, angle of repose, penetration resistance, and shear strength were quantified.

· The three iron ore samples are categorized as very cohesive to cohesive based on the ring shear test results.

· A general conclusion is that the dependent bulk properties of cohesive iron ore samples are highly sensitive to the history of the applied stress, σpre. This phenomena was observed in both ring shear and consolidation-penetration tests, in which high correlations between pre-consolidation and respectively flowability and accumulative penetration resistance are found. Therefore, choosing appropriate range of pre-consolidation in the design of equipment for handling cohesive iron ore is also crucial.
